Background technology
As logistics and the continuous renewal of warehousing system change, more efficient technical scheme, heap are constantly being pursued in market
For stack machine as the important mechanism in automatic stored, its speed of service is related to the operating efficiency of whole warehousing system, improves fortune
While scanning frequency is spent, potential safety hazard is also brought along, meeting high-speed impact track end, generation under system time control state such as piler
Huge impulsive force causes mechanical structure to be damaged.The buffer of track end installation uses liquid gas separate type or full fluid formula mostly
Structure, liquid gas separate structure difficulty of processing is larger, and reaction force is big, and effect is undesirable, shown in Figure 1, liquid qi leel from
Formula structure includes pressure pipe 1 and the separate type of piston tube 2 acts on；Full fluid formula structure uses foam sponge pressure accumulation, impact head spring
Reset, because foam sponge ageing time is fast, life of product is shorter.
The content of the invention
The invention aims to solve above-mentioned technical problem, and provide a kind of liquid gas mixed oil buffer, from
And realize it is easy to process, it is versatile.In order to achieve the above object, technical solution of the present invention is as follows：

Component content is equipped with liquids and gases, and the housing assembly includes outer shell, inner casing consistent with its axial direction in outer shell, described
One end of outer shell is provided with end cap, and the other end of the outer shell is provided with bushing, and the inner end of the inner casing is abutted to the end cap, described
The outer end of inner casing is abutted to the bushing, and buffering cavity is formed between the inner casing and the outer shell, is offered on the inner casing
Some throttle orifices, the connection cavity of the buffering cavity is communicated with the bushing, inflation group is provided with the connection cavity
Part.
Specifically, the liquid is hydraulic oil, the gas is nitrogen.
Specifically, the Buffer Unit includes being inserted into piston rod in the inner casing and located at piston through the bushing
The inner piston of bar.
Specifically, the inner end of the piston rod is provided with the back-up ring of the spacing piston.
Specifically, the inflatable component includes the valve located at connection cavity outer end, the lid located at connection cavity inner end,
The inner end of the valve is provided with steel ball, and spring is provided between the steel ball and the lid,
Compared with prior art, the beneficial effect of the gas mixed oil buffer of liquid of the present invention is mainly reflected in：Possess liquid
The advantages of gas separate structure, safeguard simple, service life length；The shortcomings that avoiding full fluid formula structure simultaneously, without using foaming
Sponge, impact head is without spring reset, and handling ease, the versatility of overall parts is high, reduces cost.

Embodiment
Clear, complete description will be carried out to the technical scheme in the embodiment of the present invention below in conjunction with the accompanying drawings, it is clear that retouched
The embodiment stated is only part of the embodiment of the present invention, rather than whole embodiments.
Embodiment：
Shown in reference picture 2, the present embodiment is the gas mixed oil buffer of liquid, including housing assembly, located at the cylinder body group
Buffer Unit, inflatable component in part and the liquids and gases being placed in the housing assembly.Liquid is hydraulic oil, and gas is
Nitrogen.
Housing assembly includes outer shell 1, inner casing 2 consistent with its axial direction in outer shell 1.One end of outer shell 1 is detachably solid
Surely end cap 11 is provided with, the other end of outer shell 1 is detachably fixed provided with bushing 12.End cap 11 is provided with the cell body of the inner end of clamping inner casing 2,
The inner end of inner casing 2 is abutted to cell body, the outer end of inner casing 2 and abutted to bushing 12, and buffering cavity 3 is formed between inner casing 2 and outer shell 1.
Buffer Unit includes piston rod 4, the piston 41 located at the inner of piston rod 4 that penetration liner 12 is inserted into inner casing 2,
The inner end of piston rod 4 is provided with the back-up ring 42 of limiting piston 41.The outer end of piston rod 4 is provided with impact head 43, the end of impact head 43
Provided with rubber noise reduction cap 44, the junction of impact head 43 and rubber noise reduction cap 44 is provided with becket 45.
Some throttle orifices 21 are offered on inner casing 2.It is communicated with buffering the connection cavity 5 of cavity 3 in bushing 12.
Inflatable component includes the valve 51 located at connection cavity 5 outer end, the lid 52 located at connection cavity 5 inner end, valve
51 inner end is provided with steel ball 53, and spring 54 is provided between steel ball 53 and lid 52.
During using the present embodiment, when impact head 43 is by external force collision, piston rod 4 promotes piston 41 to move down, in extruding
Portion's hydraulic oil, hydraulic oil are flowed out after being pressurized by the throttle orifice 21 on inner casing 2, produce damping, with moving down for piston rod 4,
